Criteria Used for Evaluation

Use

Why would you want to take your own travel sheets? Could be that the hostel you are staying in is not exactly 5 star and the sheets provided are not very nice, and who knows who slept on them last or when they were last laundered. Or maybe your hotel got the booking wrong and now you're stuck in the budget hotel down the street. If you have a sleeping bag liner with you at least you know that you can sleep inside something clean and bug-free. And it will not take up any space or any realistic weight in your luggage.

The more traditional use is as a liner for inside your sleeping bag. A good quality sleeping bag is an investment that you spend a tidy sum of money on, and it’s not the easiest of items to clean. I’m sure that your sleeping bag is very clean, and there are no strange smells when you unroll it, definitely no crumbs from midnight snacks, no squashed insect or spiders you rolled on in the night. But unless you have cleaned it after every expedition and trip then it will have a build up of body oils, bits of dead skin and hair. Basically the perfect environment for bed bugs. Most washing machines are either not big enough to hold a sleeping bag and if they are washing a sleeping bag will fill the whole machine, whereas a sleeping bag liner can be washed along with the other day to day laundry items. Much more efficient for you and the environment.

Versatility

Are you not on board with the idea? What about using a liner to boost the warmth to your sleeping bag? A bag liner can add extra degrees of warmth inside the bag.This will vary by the materials used to make the liner. Laying outside, you are about to become an all you can eat mosquito buffet. Your sleeping bag liner can double as a lighter version of the sleeping bag to give you a form ofinsect repellent.

Comfort

You need to decide on the time of year you will be using the liner. Are you only going to be using it during the spring and summer, in which case a lightweight breathable material is good? Or will you be using it in the winter and therefore need it to give the maximum increase in sleeping bag temperature and a fleece fabric might be better? The weight of the fabric may be a concern for you, as well as how small it can be packed, especially if you are going to be backpacking, however, if you camp from the car then the size and weight are probably not an issue.

What is important is that you know the size of your current sleeping bag. If you buy a liner that is larger than your current sleeping bag then you will experience folds in the liner fabric, these can be uncomfortable, but mainly it enables the liner to cling to you and as you turn over in the night the liner will slowly wrap itself around you and constrict you, like a loving Boa constrictor. Is your sleeping bag rectangular or a mummy bag? If it is a mummy bag do you want your liner to have a hood or is the hood of the mummy enough? With rectangular bags do you want a pillow pocket to insert a pillow, Is a side zip important for ease of access?

Materials

What material or fabrics should I look for? This one really depends on your personal preference, but should also be chosen based on the most likely type and frequency of use.

Silk
Silk is a natural fabric woven from the cocoon of silkworms. It is very lightweight and feels luxurious next to the skin. Silk offers excellent insulation properties, due to its low conductivity. But it is absorbent and will soak up moisture (moisture wicking) and allow this moisture to evaporate, which makes it great in hot and humid climates, as well as cooler climates. Silk is relatively strong but will lose a lot of its strength when wet so care needs to be taken when washing the material. Because of the manufacturing process to obtain silk, the cost of this fabric and items made from it are generally higher than other fabrics.

Silk-Cotton Blend
As the name suggests, it is a silk and cotton blended fabric. The main idea is to reap the benefits of both fabrics. Silk cotton blends often have the same silky feel as pure silk and the increased strength. However, the insulation properties are lower than pure silk. In hot and humid climates Silk Cotton blends still offer good absorption and moisture wicking, enabling the wearer to remain cool through the breathability of the fabric.

Cotton and Egyptian Cotton
Cotton liners are probably the most common. Cotton is a cost-effective fabric and a lot less expensive compared to silk. Cotton is great in hot humid climates and allows breathability and absorption and moisture wicking, but in terms of insulation, cotton is a long way behind the silk. Cotton liners are also heavier and do not pack as small as a silk product. Cotton does not insulate as well as silks, although the higher the thread count the better the insulation will be.

Egyptian cotton is not necessarily from Egypt but nowadays refers to the quality of the cotton thread. Egyptian cotton is a different plant than standard cotton and this along with the fact that Egyptian cotton is hand-picked changes its properties compared to standard cotton. Egyptian cotton has longer and finer strands or threads meaning that 1 square centimeter will contain more threads and as such feel finer on the skin and be more flexible and stronger. Egyptian cotton is slightly more porous than standard cotton and as such means, it is slightly more breathable than standard cotton. Expect to pay a premium for Egyptian cotton. It is worth comparing the thread count of the fabric if such information is available, this will give you an idea on the quality of the cotton. The high the thread count per cm square the better the cotton.

Synthetics
Man-made fabrics designed for a specific purpose. Some are excellent moisture wickers and breathable, such as CoolMax, others designed for excellent insulation as Thermolite fabrics are. The advantage of these is they are generally strong and easy to wash and clean. They will certainly do what they are designed for whether that is insulated or be breathable. It is worth considering these and checks if they are stretchable. Being stretchable will mean less chance of you becoming wrapped up tight because you toss and turn a lot in your sleep.

Wool Liners
Wool liners and Merino wool liners are excellent insulators, and in the case of Merino wool feel nice next to the skin. The main disadvantage is the size and weight of these.

Treated fabrics
Some liners come with special treatments and coating, such as an insect repellent treatment which is useful if you are using the liner as a summer sleeping bag.

Keep it Light

Remember when looking for a sleeping bag liner, that if you are backpacking this will be some extra weight on your pack. So keep that in mind and try to find a sleeping bag liner that is light in weight, so you can have a comfortable sleep with no extra strain on your back.

Other Factors to Consider

Weight

While the weight of a sleeping bag liner may be the last thing to cross your mind, it is still an important factor to consider. In any scenario, aside from car-camping, you will have to carry the liner in your suitcase or backpack. If you are hiking, this is a space and personal issue. If you are flying, this could be the little bit that sends your suitcase over the weight limit. While these liners don't tend to be overly heavy or space-consuming, it's still a great idea to check out the weight before purchasing.
